Abstract

The invention belongs to the field of medical instrument products, and particularly relates to a talus prosthesis. The invention provides a talus prosthesis. The talus prosthesis comprises a prosthesis body, wherein the prosthesis body is a 3D printing prosthesis body, and the surface of the prosthesis body is in an anatomical arc shape; and a plurality of protruding structures are arranged on theside of the prosthesis body and used for being inserted into healthy bones of a to-be-implanted part. According to the technical scheme provided by the invention, the 3D printing prosthesis body obtained by acquiring the information of the to-be-implanted part according to CT or nuclear magnetism data can perfectly cooperate with the to-be-implanted part in size, the protruding structures can beinserted into the healthy bones, and the talus prosthesis is not liable to loosen after being implanted, so that the short-term stability of the implanted prosthesis is effectively ensured; Furthermore, the surface of the prosthesis body is in an anatomical arc shape, and the simulated prosthesis body has a good joint function and good long-term stability. According to the talus prosthesis provided by the invention, the technical defect that in the prior art, an implanted artificial joint prosthesis is high in loosening rate after implantation is finished, is overcome.

Description

technical field [0001] The invention belongs to the field of medical device products, in particular to a talus prosthesis. Background technique [0002] Artificial joint prosthesis is mainly used in patients with ankle joint pain, deformity and loss of function caused by various trauma, autoimmune diseases and degenerative diseases. [0003] In the prior art, the prosthesis is mostly a single standard product with different specifications, and the initial stability is poor because it cannot be accurately matched with the affected area. At present, the stability after implantation is improved mainly by spraying a coating that stimulates bone growth, so that healthy bone can fuse with the implanted prosthesis. Talar joints are highly matched, irregular in shape, and have large individual differences, which often lead to unstable fixation and loosening of the prosthesis. [0004] Therefore, developing a talus prosthesis to solve the technical defect of high loosening rate aft...
